The` invention -kin its broadest scope aims toq'provide a. machineofthisnature,vr by which'the plurality yof bricks or .thelike may be formedbrconstructed .at .one time. V

A further object `of the.inventionisuthe provision of aunovablememberhaving)V a number of compartments, which receives the plasticmaterialfor forming the bricks.

,A further objectbf the invention is .to provide a front plate forcooperating with theuruovable member whereby the bricks may-becompleted, which front plate, when throwninoperative position operatesthe movablel member. K .I n

A feature ofthe invention theprovisionof-,a vertical movable crossheadhavinganumber of transverse plates,to yfurtherV completethe bricks,the same being operated byafoot pedalf.. E y V In thedrawings: there isdisclosedpnly one form ofthe invention., but in practical tieldslthisform may necessitate alterations, to.y which the patentee is entitled,provided the alterationsA are. comprehended within thefscope ofwhat is.claimed.

The invention comprises `-further features and combination of parts,as'u hereinafter set forth, shown in the drawings and claimed.

Fig. `3 is a vertical sectional ,view on line 2-2 of Fig. l. Fig. 4: is a sectional ,View on line of Fig. l; Fig. 5 isa sectional view on line 5.5 ofFig. 2. i

vReferring more specifically tothe drawl designates the main frame,which may be. of any desired construction and contour, but preferably,constructed,l of angle sheet .met-al and plainbars,as shown at 2, 3,4and This framesupports aplateG, the rear portion of which upon its upperE surfacel is provided with a series of grooves @,which extend for halfthe length of the plate,that is, from substantially the center portionof the plate reaiuvardly.v This plate G is also constructed with a slot50', the purpose of which will hereinafter appear. The l'forwardportionof the `platehas its upper l, surface disposed belowthe bottomskof the grooves 6b, as shown and disposed upon this upper surface oftheforward portion of the platei is the ybed plate 6a, the upper surfaceofsaid grooves 6b, the purpose of which will appear later. Jabove theplate 6 a. supplemental frame 'Y .is supported by thebars 8, that`is,paboveV the, rear portion of the plate 6. VThis supplemental frame 7supports'a hopper v9 ofjgalvanized sheet iron, through whichl theplastic material is passed into the pluralityof compartments l0 of themovable'member 1l. This movable member 11 reciprocates upon the upperrear surface of the ,plate 6, the `divisional plates y12 (whichform-thecompartments 10) of the member llslide. in the grooves 6b.However, when the movable member is moved forwardly, the divisionalVplates 12 lslide 'from the grooves 6b forwardlyV and upon the ybedplaten@L as shown in Fig. 2.'. The movable member, however, is movedforwardly' after the compartments. 10 have been filled with the plasticmaterial. 'Y

y Carried by thesides of the main frame, two. on each side, yare thebrackets 13, in whiclrthe side tubular bars 14e of the U- shapedframeMare seated. These side tubular bars are secured in the brackets. by thebolts i6. `Slidable on theV side tubular bars is the cross head 18,there being two bars 19 and 20, which constitute the cross head; vwhile,the annular members .21' (which are bolted at 22 to the bars 19 and 20)constitute the sliding bearing. Secured to the cross bars 19 and 2O arethe vertical plates 23, at the lower ends of which the transverse plates2% are rigidly secured. The plates 24 shape and smooth one side ofthebricks, when brought in operative position asshown in. 1.while thecompartments 10. formy two sides and an end of the brick. The base plateforms the side of the brick opposite the sides formed by the plates 24.The vertical. plates are furthersecured `to `the cross bars 19,.and 20the crossing bars Connecting the end "vertical plates 28 is a U-shapedhandle 26, which of'whichjis flush or even with the bottoms and theunder portion of the bed plate,

which prings normally hold the trcadle and the cross head in theirraised position. The cross bar rll is connected to the treadle by theU-shaped members 32.

`lilounted in bearings 33 of the main frame is the shaft 34. Pivoted onthe shaft is the liront plate 35, which is provided with the i plates56. rEhe plates 136 are equally spaced g apart, as shown at 37, so as toreceive the forward edges of the division plates 12 of the movablemember l1, that is, when the liront plate 35 is closed as in Fig. l.This front plate is pii'ovided with handles 38, by which the same may beswung on the pivot rod or shaft 34. These handles beyond theirconnection 39 with the rod 34. are provided with approximately rightangle extending arms 40, between which and the movable member ll thelinks 4l are connected.

The pivot connections 40e and 40f between the links 4l and the arms 40of the levers 38, and the member ll, are arranged in a plane above therod 34, as shown in Fig. 3,

by the dotted line 40, so as to hold the front tation. lt will beobserved that, as the front i plate 353 is swung downwardly as shown inFig. 2, the movable member l1 will be simultaneously moved rearwardly.The front plate when closed locked in position by the U-shaped lever 43,which is pivoted at 44 between. the arms 44h and the supplemental frame7. The rear ends of the bars of the U-shaped lever 4B have slot and boltconnections 45 with the arms 4G, which project upwardly from the plate 6upon each side of the machine. The slots of the slot and boltconnections between the arms 46 and the U-shaped lever limit the upwardmove nient of the forward end of the U-shaped lever 43.

When the liront plate 35 is closed as shown in Fig. l, the notches 46aof the U-shaped lever 43 engage the recesses 47 of the two end plates36, so as to hold the front plate locked, until the bricks have hardenedsufriciently. By virtue of the slot and bolt connection 45, the U-shapedlever 43 may be tilted upon its pivot 44, so that the front plate may beopened. The U-shaped lever 43 provided with a. handle 48, by which thelever may be raised.

Traveling over the pulleys 49 is a Cable 50,substantially the centralportion of which is secured at 50e to an arm Of (which moves bacluvardlyand forwardly in the slot 50 when the member ll is reciprocated) securedat 50g by any suitable means to the member 1l. One end of the cable isprovided with a weight 5l, while the other end is connected to the crossbar 3l of the treadle 27 by means of the hook 52. After the U-shapedlever 43 is raised, thus releasing 'the front plate 35, the movablemember ll may be moved rearwardly and the liront plate thrown downwardlyby the gravitation of the weight, that is, when the handles or levers 3Sare partially moved outwardly and downwardly upon the pivot rod 34manually until the pivot 40C is below the plane between the pivot rod 34and the connection 4.0i. Then the weight will act to move the member 11rearwardly and the front plato downwardly, the operators foot havinglirst been removed from the tl'eadle. lWhen the operators foot isremoved from the treadle, the cross head with the plates 23 and 24 willbe thrown to their uppermost positions, thereby leaving the bricks uponthe' bed plate 6a ready to be removed.

Operation: ln operating the machine the parts thereof assume positionsas shown in Fig. 2, that is, without any bricks upon the bed plate 6a.Wvhen the parts are so arranged the movable member 11 with thedivisional plates l2 forming the compartment 10 are under the hopper 9,the divisional plate being` received in the slots 6l. The plasticmaterial is then placed in the hopper passing therethrough into thecompartments l0. The operator then throws the handles or levers 3Supwardly, and owing to the arms 40 being connected to the links 41 at40e, which links in turn pivotally connect at 40f to the member ll, themember l1 will be moved forwardly, the divisional plates l2 passing fromthe grooves 6b upon the bed plate 6a, the compartments l0 carrying theplastic material forwardly. lil/'hen the handies or levers 38 are movedupwardly to the positions in Fig. 3, the front plate 35 is closed, andowing to the pivots 40e being on a plane above the rod 34, as shown bythe dotted line 48, the front plate 35 and the member 1l will be heldclosed or locked. The weight tending to pull the member ll rearwardly,will render the locked or closed positions of the member l1 and thefront plate 35 more secure. rlhe operator then presses upon the treadleagainst the action of the springs, thereby lowering the cross head andthe plates 23 and 24. ln this manner the bricks are formed. Alfter the'front plate 35 is closed, the lJ-shaped lever 43 is moved downwardly,so that the notches 46a ot the U-shaped lever will engage the recesses47 of the two end plates 36, thereby llio llo

llo

holding the front plate more securely locked, until the'bricks havehardened sutlicien'tly, To permit the bricks to harden, while all thebrick forming parts are closed, the treadle may be held down b y anysuitable means such as a catch or the like (not shown). After the brickshave settled or hardened sufhciently, the handles or levers 38 may bemoved manually partially outwardly, after first having raised theU-shaped lever 43 until the pivots 40e are below the plane of the shaftor rod 3l, then at this period of opening the brick forming parts of themachine the treadle may then be released, and by means of the weight themember l1 and the frontplate 35 will be thrown simultaneously to openposition, and at the same time by means of the spring-tensioned treadle,the cross head together with the plates 23 and 24 will be raised.However', the treadle need notbe held downwardly for any period of time,but after being depressed, so as to throw the plates 24 downwardly, soas to produce smooth surface upon the plastic material of the bricks,the treadle maybe reileased, vandV the plates 24 thrownupwardly,

in this case the cable or rope between i the cross bar of the treadleand the arm 50t will become loose, but nevertheless the member 11 andthe front plate 35 will be held securely closed or locked, until it isthought the bricks have sufficiently hardened, after which the frontplate 35 may be thrown partially outwardly, and as the pivots 40e passbelow the shaft or rod 34, the weight will then act to throw the frontplate 35 completely downwardly and the member 11 fully rearwardly.k Bymeans of a sudden and forceful pressure upon the treadle all of themovable brick forming parts may be closed simultaneously, even throwingthe member 11 and the front plate 35 to their locked positions, and thenby any suitable means (not shown), as above stated, the treadle may beheld downwardly.

From the foregoing it will be observed that there has been produced anovel, efficient and simple machine for constructing bricks, and onewhich has been found to be practicable.

Said series of plates i4 when thrown downwardly are clamped between themember 11 and the front plate 35. This is one way for holding thetreadle depressed.
